In a groundbreaking step for exoplanet science, NASA's James Webb Space Telescope (JWST) has given us an unprecedented look at the atmosphere of TOI-421 b, a sub-Neptune exoplanet about 245 light ...

“As a team that truly loves Alien, we’re incredibly proud of the immersive original story we’ve told with Alien: Rogue Incursion,” said Survios chief product officer TQ Jefferson in a ...

Mysteriously, ... Apr. 15, 2025 — A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded ...

TOI-270 d is an exoplanet discovered by the Transiting Exoplanet Survey Satellite (TESS) mission of the National Aeronautics and Space Administration (NASA). TESS uses a transit method to discover new ...

Astronomers targeted TOI-421 b because its high temperature which is estimated to be around 727°C, that suggested a clearer atmosphere. Earlier studies had hinted that hotter sub-Neptunes may lack the ...

NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to precisely analyze molecular components such as water vapor and sulfur dioxide in exoplanet atmospheres. The key to this ...

Some massive exoplanets' cores could contain over 100 Earth masses of solid material. These planets likely grew so large and contained so much metal because they collided and merged with multiple ...
